Nervous System

What does the axon carry?

• Impulses away from the cell body

• Impulses to the cell body

• chemicals

• messages

What do the motor neurons do?

• carry messages from the brain and spinal cord to muscles and glands

• carry impulses from skin and sends to organs the to spinal cord and brain

• carry impulses from sensory neurons to motor neurons

• store messages

What is the central nervous system made up of?

• brain and spinal cord
• cranial and spinal nerves
• sensory and motor systems
• sympathetic and parasympathetic systems

Which system controls involuntary responses?

• somatic
• autonomic
• sympathetic
• parasympthetic

Which structure connects the Brain to the Peripheral Nervous System, while also directing some of the body's reflexes?

• Spinal Cord

• Esophagus

• Pharynx

• Larynx

• Trachea

The Peripheral Nervous System is entirely made of

• Nerves outside of the Central Nervous System

• Nerves inside of the Central Nervous System

• Muscle Tissues inside of the Central Nervous System

• Muscle Tissues outside of the Central Nervous System

Which part of a Neuron detects neurotransmitters?

• Dendrites

• Nucleus

• Axon Terminal

• Myelin Sheath

Select the answer that is in the correct order.

• Stimuli, impulse sent down a neuron chain, brain makes decision, sensory neurons detect a change in the environment, muscles move accordingly

• Impulse sent to brain, receptors detect information, Motor neurons send an impulse to a muscle group

• Stimuli, sensory neurons detect information, inter neurons in the brain relay the information, motor neurons send an impulse to a muscle group

What is the purpose of the myelin sheath on the axon?

• To maintain temperature
• To improve conductivity
• To protect the axon
• To release neurotransmitters

What is NOT part of the peripheral nervous system (PNS)?

• axons
• sensory receptors
• spinal cord
• motor neurons
